LCA of scrap CRT display at various scenarios of treatment

With the development of the science, technology and economy, electronic products became the important necessary products in daily life. Due to the large usage of electronic products, generation of the e-waste became more and more. The e-waste treatment was generally as a troublesome task. The life cycle assessment (LCA) method is used to analyze the treatment technology of cathode ray tube (CRT) display. The results show that the environmental impact of incineration of CRT display has the greatest impacts, with comparison to the manual-based dismantling and mechanical recycling. The impact of Carcinogens is the major contributor, which cause a direct impact on human health. The result suggests that the CRT display should be separately treated and not be mixed with municipal solid waste which is treated by incineration.
